Method, device and system for setting wavelength path are provided by the present invention. The method includes: updating signaling message according to physical signal damage parameter information and adjustable physical signal damage parameter range information of the adjustable unit in the wavelength path during process of setting the wavelength path; the destination node judging whether or not the signal quality meets the destination node signal quality threshold according to the physical signal damage parameter included in the signaling message, if it does meet, each node of the current route setting wavelength path based on the current route, otherwise making a further judgment that whether or not the signal quality would meet the destination node signal quality threshold by adjusting the physical signal damage parameter in the adjustable physical signal damage range parameter, if it does, informing relative nodes in the current route to adjust the physical signal damage parameter, and then each node of the current route setting the wavelength path based on the current route. Method, device and system for managing wavelength path are also provided by the present invention. |
